To all whom it may'concem: I Be it known that I, GILBERT E. Fnnni', a, citizen of the United States, residing at- Omaha, in the county of Douglas and State '01 Nebraska, lnive invented certain new and mseful Improvements in AngleBraces for Screen-Frames, of which the following is a. specification.

This invention relates to improvements in angle braces for screen frames, and has for its object the provisionof a brace which may be conveniently constructed and ma be manufactured without waste oimatel'lal.

Another object is the provision of an article of this class which may be used for bracing the corners and also the cross strip of a screen-frame.

The material used is preferabl sheet metal, it'is comparatively inexpensive, and has an adequate strengthsince it is an integral structure, and,\by reason of the transverse disposition of the several parts, the walls coo crate to reinforce each other.

With these and other objects in view the invention consists ofthe novel combination and nrran ement of pnrts'as described herein, pointct out by the claims, and as illus' lmtetl in the drawing, wherein,-

Figure 1 is a plan view of a metal sheet or plate used for mnkin a single brace; the incised and'bent arts being indicated respectively, by soli and broken lines. Figs. 2 and 3 are perspective views of an angle bra e embodying my invention. Figs. 4 and 5 are perspective views showing these braces mounted upon the horizontal end-stn'p and vertical side-strips of a screen frame Figs 6 and 7 are perspective'views somewhnt similar to Figs. 2 and-3, and showing the endextensions of the brace bent to occup the same plane as the sides, and used as a race upon the cross strip and vertical strip of a screen frame. Figs. 8 and 9 are perspective views illustrat-in operative mounting of the braces last nam Fig. 10 is a side view of a screen frame, showing the braces mounted by nails within openings 18, flanges h ,21 is shown in Figs. 6, '1, 8 angle brace is the some as already described or flanges v sides 4 upon the vertical slde stri s, and horizontal be line b b,-'and'thereafter bent snbstentialg uponedjeoentlines, parallel wi line a at, indicated at c c, d d, form a rectan lar bait 3 with a terminal 27, and witfi adjacent, integral, parallel sides 4 and to form end-portions 5 with oppositelyfiis posed, transverse extensions, wings or flan 6, each of sides 4 having an angular incision e f 9' intermediate its ends and opening upon its side edge and bent "on line e h to form the extensions or wings 7 of end-portions 5,

with transverse adjacent flan s 8 thereon.

of vertical side-strip 12, as shown in Fig. ..10, back 3 may outer face 13 of said end-strip, extensions 6 be seated inclosingly upon the occupying the same plane as the back and i being seated. upon terminal 14 of vertical strip 12, and may be secured by use of suitable ins or nails in openings 15, and sides 4 wil-Fhave seatings upon the outer and inner sides of said horizontal strip, secured by nails in openin s 16; and ends 5 with extensions will sides 17 of strip 12, flanges 8 eing seated upon the inner sideof tiis strip and held 19 bein seated upon the inner side 25 o orizonta ave seatings u on opposite end-strip l0, and held by nails or: pins in openings 20. The angle brace thus described may be construct ve economically, and operates din means for use upon cornersof the screen me. "i t t To illustrate economy of mliterial in mam ufacture and convenience in use, angle brace and 9. This exec t that extensions b, above mention are m outward dogma toprovide arms 6, displosed upon-the seine plane as and w en thus bent,'back 3 me zontal cross piece 24, w its outer terminal 27 in engagement with the inner face 11 of strip 19, and sides 4' may be seated u on the outer sides 23 of said cross piece an secured thereon by nails passed within openhaving seatings upon the lower face'26 of cross-piece {and flanges 19 may be secured by use of pins or lbs Q sposed upon the upper face 22 of hon nails assed within openin 20'; and ends 5 an extensions 7' thereo will have seatings UK) sides 17 of strip 12, lianges 8' thereo having seatin s upon the inner side 11 of this strip seeu re by nails or like memhers within openings 18. As thus eon strueted and mounted the device provides a holdin means for the cross piece .upon the verticfi strip, convenient in use and effective in operation, and when securing together the several strips shown in Fig; 10, braces 2 and 21 may be used interchangeably by raising or lowering flanges 6 or U to the positions described, as required, for securing together the corners, or to secure an intermediate cross-stri I upon the vertical strips of the frame. it will be noted that the metal plates or sheets 1 may be of the same size and shape, and are incised the same, for the formation of either of the herein described an le braces.
